Hello, you are missing a " after (name) ;-) =

let greeting= "Hi there, (name)"

To avoid this problem in the future, I have a little trick, i always put the 2 "" and then write in the middle. same for () and {} and []

Hi!

You need to close the string with another " mark at the end:

let greeting = "Hi there, \(name)" // <- that's missing!

sorry I dont know how to include the screen shot. but anyway I typed the following..

let name = "Joe"

let greeting = "Hi there, \(name)"

also tried..

let greeting: String = "Hi there, \(name)"
let greeting = "Hi there," " \(name)" 
let greeting = "\(Hi there), \(name)"

let greeting = "\(Hi there,)"  "\(name)"
let greeting: String = "\(Hi there), \(name)"
let greeting: String = "\(Hi there)",  "\(name)"
let greeting: String = "\(Hi there,)"  "\(name)"

all sorts of variants.

Hi Joe,

I think you start with creating a name constant:

let name = "Joe"

Then you want to interpolate name into a greeting constant (just like you've done in your first lines?!):

let greeting = "Hi there, \(name)"

However, I've just tried this and it isn't working - this is the third Swift issue I've come across tonight - I think there may be an issue with the challenge. Let me get hold of support ...

if you look at my previous reply I did type

let name = "Joe" the greeting is what I changed to try variants of syntax. I just left out, let name = "Joe" to keep the message/reply short.

Yep - I can see that you've solved the challenge correctly but highlighted that there's an issue with the Swift backend at the moment; I have advised Support.

Jennifer Schultz yes, it was fixed the same evening. I hope you got going again; I assume you did as your comment has gone.
